Mapping of Single NV Centers Using Tunable Electric Field Saddle Points

The project will develop and test a novel technique to precisely determine the position of quantum emitters in diamond, specifically nitrogen-vacancy (NV) centers, which are among the most promising building blocks for future quantum technologies. This method leverages tunable electric fields and Optically Detected Magnetic Resonance (ODMR) to map NV centers with accuracy better than 10 nanometers, a significant improvement over traditional optical imaging techniques restricted by the diffraction limit. By enabling deterministic localization of individual NV centers, the approach lays the foundation for scalable quantum devices such as quantum sensors, secure communication nodes, and single-photon sources for high-fidelity qubit generation. The University of New Brunswick will contribute expertise in simulations, electrode design, and experimental techniques such as electron beam lithography and ion implantation, while the University of Sheffield will provide access to advanced nanofabrication and optical characterization facilities. This collaboration will not only strengthen both institutions’ research capacity but also accelerate the development of next-generation quantum technologies, while creating unique training opportunities for students in cutting-edge experimental and computational methods.
